TONSILOTOME.

Patented Dec. 15, 1908.

Serial No. 442,075.

To all who/m, it may concern:

Be it known that I, RHoDoLPHUs H. RICE, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented a new and useful Im rovement in rIonsilotomes, of which the ollowing is a specification.

My invention relates to improvements in surgical instruments, designed especially for the removal of enlarged or diseased tonsils, adenoids, etc. Y

The object of my invention is to provide means whereby the part to be removed may be first gripped by an encircling band, such as line wire, and either cut through by drawing in on the wire, or the diseased growth pulled off, as desired by the surgeon.

In the following description, reference is had to the accompanying drawings in which- Figure l is a plan view, part in section, of a surgical instrument embodying my invention. Fig. 2 isV an edge view of the instrument. Fig. 3 is a sectional view (major section) drawn on line 3--3 of Fig. 2. Fig. 4 is a detail view of one of the wire supporting ins. Fig. 5 is an enlarged end view of the raw bar, showing the wire connections in cross section. Fig. 6 is an enlarged detail plan view of the end ortion of the draw bar, showing the ends o the wire, with dotted lines indicating their position when partially folded.

Like parts are identified by the same reference characters throughout the several views.

A supporting member A is preferably provided with a handle B at one end, and at the other end with a tubular or channeled portion C constituting a narrow extension of the holding member, terminating in a flat, round or oval shaped member D, which is provided with an opening E through which the tonsil, or part to be removed, is caused to project. A series of pins F extend outwardly from one surface of the member D, and a draw bar G, slidingly mounted in the channeled portion C, extends over said surface, and is connected with a band of fine wire H, which is primarily passed around the pins and is thus held in a position to encircle a tonsil projecting through the aperture. The outer surfaces of the pins may be beveled or incined inwardly, as shown in Fig. 2, or forked and provided with a tapering inner arm f as shown in Fig. 4, the arm f of the fork preventing the wire from moving downwardly to the base of the pin. In either case, the construction is such that by drawing forcibly upon the bar G, the wire may be withdrawn from the ins. The bar G -is provided with a series ot teeth g along one side, and a resilient catch J engages these teeth and holds the bar from moving toward the outer end of the tool. An actuating bar K, provided with a handle L, extends through a guide bearing M on the supporting member, and is provided with teeth fm, adapted to engage the teeth g on the draw bar. O is a spring to facilitate holding the bars together, while permitting them to separate when securing new adjustments.

In operation, the wire is first assed around the pins and the ends inserted tllirough diago- ,nal holes at P in the draw bar. The apertured member D is then adjusted over the tonsil and the latter arranged in a position projecting through the aperture. The hanle L is then drawn backwardly until the wire sli s from the pins, the ends of the wire being ent backwardly during the initial movement by contact with the ortion C, and doubled into channels Q in t e sides of the draw bar, thus locking the wire t0 the bar. The tonsil having been gripped by the wire, the handle L is moved outwardly along the support until the outer end of the actuating bar K approaches the part C, where it reengages the teeth on the draw bar G, when by drawing backwardly upon the handle L, the wire cuts through the tonsil. Where an adenoid is to be removed, it may be engaged by the wire and by ulling backwardly upon the support, it can be wholly torn away.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is- 1. In a device of the described class, the combination of a supporting member, an apertured member connected with one end thereof, a guide on the supporting member, a draw bar extending through the guide to the apertured member and retaining devices on the apertured member arranged to hold a piece of wire in a position encircling the aperture, the ends of said wire being connected with the draw bar,-together with a movable handle and an actuating bar connected therewith and adapted to engage the draw bar in various positions of adjustment.

2. In a device of the described class, the combination of a holding member provided with a narrow extension, having a guide way extendingr longitudinally thereof, a fiat member provided with an aperture therein and connected with the outer end of said extension, a set of pins projecting from said apertured member and having` inwardly inclined faces, a draw bar mounted in said guide way, a wire connected vwith said draw bar. at both ends and extended around said pins in a manner to encircle said aperture, means for actuating said draw bar, and a catch to prevent retractive movements thereof.

3. ln a device of the described class, the combination of an apertured member, means for retaining a wire in a position encirclingr the aperture in said member, a support for said apertured member and a device movably connected with the support and adapted to engage and draw the wire from said retaining means across said aperture, said retainingr means comprising a set of pins, each provided with a forked extremity, adapted to receive the wire, the inner arm of the fork being provided with an angular face adapted to release the wire when the latter is subjected to the desired tension.

4. In a device of the described class, the combination of an apertured member, wire retaining devices mounted thereon, a wire supported by said devices in a position encircling said aperture, a supporting member, and a draw bar mounted on said supporting member provided with perforations in one extremity, through which the ends of the wire pass, said draw bar being provided with channels in its side margin at the perforated end and said supporting member being provided With guides for the draw bar, ada ted to engage the wire and bend it into said c annels, when the draw bar is retracted,-the retaining devices being adapted to release the wire during the retractive movement.

ln testimony whereof I afIix my signature in the presence of two witnesses.
